Making trust computable.
We're building the trust layer for AI-mediated commerce — open, verifiable infrastructure that helps autonomous AI agents evaluate businesses based on facts, not opinions.
Mediary is an open trust infrastructure protocol built by SpottMedia. It verifies 8 trust signals for businesses and publishes machine-readable Trust Readiness Index (TRI) scores that AI agents use to decide which businesses to recommend. The protocol is MIT-licensed with no vendor lock-in. See how businesses benefit from AI visibility, or explore our transparent pricing.
The problem we see
Commerce is shifting from human-browsed to agent-mediated. When an AI agent recommends a restaurant, books a service, or compares suppliers, it needs to evaluate trust programmatically. But there's no standard way for a business to present verifiable trust signals to an agent.
The tools that exist — Google Business Profile, Yelp, Trustpilot — were designed for human audiences. They rely on reviews, star ratings, and self-reported information. None of that is structured, verifiable, or machine-optimised.
What we're building
Mediary is a trust infrastructure protocol. It evaluates 8 verifiable signals for any business and publishes a machine-readable Trust Readiness Index (TRI) that agents can query via API.
Think of it like SSL certificates for trust. SSL didn't replace websites — it made websites trusted by browsers. Mediary doesn't replace your online presence — it makes your business trusted by AI agents.
Our principles
Protocol-first, not platform-first
Mediary is an open protocol. Any agent can query it. Any business can claim their profile. We don't want to be a walled garden — we want to be a standard.
Verified facts, not opinions
Every signal in the TRI is based on observable, verifiable data. No reviews, no sentiment, no subjective scoring. The same inputs always produce the same output.
Infrastructure, not marketing
We're not selling visibility, ranking, or promotion. We're providing the structured data layer that agents need to make informed decisions. The agent decides what to do with it.
Who builds Mediary
Mediary is built by SpottMedia, a platform engineering company with over 15 years of experience building infrastructure for web applications. We build trust systems because we believe the shift to AI-mediated commerce needs an open, verifiable trust layer — not another walled garden.
Our vision
Every business has a trust profile. Every AI agent can read it. Trust is computable, open, and verifiable — not a popularity contest or a pay-to-play marketplace.
